Honey I have had huge amounts of red blood and passing clots too in previous pregnancies. and my dd was fine!

a series of 3 or 4 hcg tests taken every 48 hrs may be more helpful to see the levels rising.

i have had many scares this time round, including passing clots which i was sure meant the end for my baby, but had a scan today and all is fine!

Dont give up on your little one. sometimes they are toughter than we think.
